Mi-t-m 25-0608 Viton O-ring G55 Outlet Valve Seal

Product Description

The MI-T-M 25-0608 is a Viton O-ring sized G55, designed to seal the outlet valve on the first stage of MI-T-M pressure washing and power cleaning equipment. Viton compound is a fluoroelastomer material well suited to high-pressure environments where petroleum-based fluids, detergents, and temperature cycling would degrade standard nitrile or EPDM seals. This O-ring provides a critical pressure boundary at the first-stage outlet, preventing fluid bypass and maintaining system efficiency. It is a direct OEM-style replacement part installed by pressure washer service technicians and trade professionals performing pump or valve rebuilds.

This O-ring is used in the first-stage outlet valve assembly of MI-T-M pressure washing units. It is typically encountered during scheduled pump maintenance, valve rebuild service, or whenever a technician identifies a leak at the first-stage outlet port. The G55 designation corresponds to a standardized metric O-ring size, and the Viton compound makes it suitable for use in hot water or steam-rated systems as well as cold-water models where chemical resistance is a priority.

Key Features

• Viton fluoroelastomer compound offers superior chemical and heat resistance compared to nitrile or EPDM alternatives
• G55 standard sizing ensures consistent fit in the first-stage outlet valve seat
• Designed as an OEM replacement part for MI-T-M pressure washing equipment
• Resists degradation from detergents, cleaning agents, and petroleum-based fluids
• Critical sealing component that maintains first-stage pressure integrity during operation

Compatibility

Designed as an OEM-style replacement for the first-stage outlet valve assembly in MI-T-M pressure washing and power cleaning equipment. Consult the equipment service manual or MI-T-M parts diagram to confirm fitment for the specific unit model before installation.

Installation Notes

Installation should be performed by a qualified pressure washer service technician familiar with pump valve rebuilds. Before servicing, relieve all system pressure, shut off the water supply, and disconnect the unit from its power source or fuel supply. Inspect the valve seat and bore for scoring or debris before seating the new O-ring, and apply a compatible lubricant to ease installation without tearing the seal. Do not use petroleum-based greases that may degrade elastomer compounds.
